TPS62869EVM-118 Evaluation Module
This user's guide describes the characteristics, operation, and use of TI's evaluation module (EVM) for the
TPS628691, TPS628692, TPS628681, TPS628682 devices. The TPS62869EVM-118 (BSR118) facilitates the
evaluation of the TPS62869 family of 6-A, step-down converter with DCS-Control
QFN package solution. The EVM creates output voltages between 0.4V and 1.675V with 1% accuracy output
voltages from higher input voltages between 2.4 V and 5.5 V, to a regulated 0.9V output voltage. The TPS62869
family is a highly efficient and tiny solution for point-of-load (POL) converters for space-constrained applications,
such as artificial intelligence chips, camera modules, solid state drives (SSDs), and optical modules.
